Security Bulletin

Summary

IBM RackSwitch firmware products listed below have addressed the following
vulnerability in OpenSSL.

Vulnerability Details

CVEID: CVE-2018-0732
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
sending of a very large prime value to the client by a malicious server during
key agreement in a TLS handshake. By spending an unreasonably long period of
time generating a key for this prime, a remote attacker could exploit this
vulnerability to cause the client to hang.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144658 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
